A 90-year-old man dissatisfied with the service at a Florida post office yesterday pointed a handgun at a worker and threatened to “blow his head off,” police charge.

HB Shea, the accused nonagenarian, was arrested outside the post office in Boca Raton by Palm Beach County Sheriff's Office deputies who seized his weapon. Shea lives in a nearby condominium development.

Pictured at right, Shea was initially transported to a local hospital for a medical evaluation before being booked into the county jail. He has been charged with aggravated assault and a pair of weapons counts (for which bond has not been set).

Shea could also face a federal charge related to his carrying a handgun into a post office.
